Neodymium disc magnet, 1.5mm x 0.5mm, N50

A neodymium magnet is a ferromagnetic material. In terms of magnetic properties, it belongs to the most stable magnet types. The neodymium magnetic alloy consists of microcrystalline particles that are placed in a strong magnetic field during production, so that their magnetic axes point in the same direction .   In terms of its magnetic values, it significantly exceeds the values of traditional strontium ferrite (by 18 times the value) and the first   rare earth magnet first   generation, Samarium-cobalt magnets as well.

Designation of the type ( N ). The magnet type has a high tendency to corrosion, so it comes off the production line with surface protection.   Higher values indicate stronger magnets (eg: N48). There is a widely known international classification for sintered NdFeB magnets. Their values range from 35 to 52. Values come first _   N letter   stands for neodymium, meaning sintered NdFeB magnets, e.g. N52.

It lies in rare earth magnets   these forces can carry great dangers. Neodymium magnets larger than a few cubic centimeters are strong enough to cause injury to body parts caught between two magnets, even bone fractures . Ingestion of magnets can cause death, if this happens you must consult a doctor immediately .
